Elastic-wave propagation through disordered and/or absorptive layered systems

Using the transfer-matrix method, we study the propagation of elastic waves through disordered solid multilayers constructed from two different materials and assumed periodic on the average. Results for different incident angles are reported; the effect of the mixing between longitudinal and transverse type of waves in the case of incident angles different from normal is discussed. We also study absorbing systems and how the localization length changes in the presence of dissipation.
